OFF-BEARING MACHINE Patented April 28, 1908.

Renewed September 6, 1907. Serial No. 391,699.

To all whom it may concern:

Be it known that I, WILLIAM R. WAG- GONER, a citizen of the UnitedStates, residing at Brazil, in the county of Clay and State of Indiana,have invented certain new and useful Improvements in Off -BearingMachines, of which the following is a specification.

This machine relates. to improvements in off-bearing machines for greenconduits, tiles,

and other clay products which issue from a suitable machine in anunbroken stream, to be afterwards cut into sections of the desiredlength, and the object of the invention is to provide means whereby thisconstant output can be cut into the required lengths and removed easilyWithout stopping the mill.

The further object is to provide a simple, durable and easily operatedmechanism such as will be hereinafter fully described and the novelfeatures of which will be pointed out in the claims.

Referring to the accompanying drawings which illustrate my invention andform a part of this specification,--Figure 1 is a perspective view of mycomplete invention in its compact or closed osition. Fig. 2 is a planview of same in li eposition and showing the movable platform in dottedlines in its open or outer position. Fig. 3 is a side elevation of thedevice in expanded or open position as viewed from the stationarylatform. Fig. 4 is a longitudinal vertica section through the tables andmovable latform showing the said parts in their 0 osed or closestrelation to the mill and to each other. Fig. 5 is a detail in likesection showing the shield for deflecting such material as may workthrough the table to otherwise clog the underlying rack and wheel. Fig.6 is a transverse section on the line 5, 5, of Fig. 4. Fig. 7 is aperspective View of the cut-off and apart of the rocking shaft. Fig. 8is a side elevation and Fig. 9 a lan view of the specially constructedtrue with its adjustable table in position to receive the clay product.Fig. 10 is a side elevation and Fig. 11 a plan View of same with thetable in position preparatory.

to dumping the load. Fig. 12 is a side elevation of the truck with aload dumped and the truck ready for withdrawal. Fig. 13 is a perspectiveview of the truck with the addition of an attachment for holding theclay articles by friction. Fig. 14 is a detail in perspective of acorner of the truck-table and Fig. 15 is a perspective View of one ofthe removable standards for holding the pallet.

Like characters of reference indicate like parts throughout the severalviews of the drawings.

1 represents the mill which is here shown as a lunger-mill but ingeneral will be an auger mill of any of the usual and suitableconstructions.

2 are the rails of a track extending outward from the mill. These railswill preferably be T-iron or steel, inverted as clearly shown in Fig. 6.A table 3 supported on the legs 4 has the axles 5 which are mounted insuitable boxes at the lower ends of the legs. Flanged wheels 6 aremounted in a fixed manner on the axles and have their bearings on therails 2.

Between the table 3 and the mill 1 is the table 7 having the legs 8which terminate with boxes to receive the axle 9 on which are the fixedwheels 6 which also have their bearings on the said tracks. The table 7is maintained with its top on a level with the to of table 3 by means ofthe slide-bars 10, w ich pass between the horizontal cross-bar 11 andtransverse roller 12 of table 3, in the manner shown in Figs. 4, 5, and6. The complete withdrawal of the slide-bars 10, and consequentseparation of the two tables is prevented by the lugs 13 which contactwith the cross-bar 11 and form stops to prevent separation. Both tablesare surfaced with sheet metal which imparts a smooth surface to theproduct. These surface sheets are supported upon longitudinal bars 14which in turn rest upon the cross-bars 1 1.

Projecting outwardly from the sides of the table 7 are the pairs of lugs16 and 17, which are spaced a suitable distance apart to form stops tolimit the movement of the table 3 on the tracks. This limitation iseffected by the contact of the lugs with stationary posts or standards18 which terminate between said lugs in the manner shown in Figs. 1, 2,and 3.

Running parallel with the rails 2 is the third rail 18*, and mounted onrail 18 and the far one of the two rails 2, are the four flanged wheels19. The wheels 19 are fixed on the axles 20, which axles are mounted inboxes that are supported and carried by the platform 21. The platform 21is thus movably mounted on the above-described tracks. Attached to theplatform and extending under the tables 3 and 7, parallel with the railsof the track is the rack-bar 22, and supported by the fixed standards24, located on each side of the table 3, is the shaft on which ismounted the fiXed spur gear wheel 26, the teeth of which engage the cogsof the rack-bar 22. The shaft 25 also has the ratchet wheel 27 mountedin a fixed manner outside of standard 24, and the crank 28 mountedoutside of the ratchet wheel. A pawl 29 having the handle extension on.lever 30 is brought into contact with the teeth of the ratchet wheel byraising the handle, thereby preventing the rotation of shaft 25 in thedirection which would move the platform 21 away from the tables. Byrotating the shaft 25 in the opposite direction the platforlm 21 isdrawn along the track toward the mi l 1.

32 is a vertical post carried by the platform 21, and 33 is a wheeledtruck carrying a table 34 which comes opposite a roller 35 mounted onthe top of the post 32, when the truck is in proper operative positionon the platform. Then, when the platform 21 is drawn toward the mill 1,the table of the truck is pressed by the roller 35, against the end ofthe table 3, and that table against the table 7, and the whole movableconstruction is forced along the tracks until all are arrested by thestandards 18. The above parts are then in their closest relation to eachother and to the mill and are retained in that relation until a finishedconduit section has been pushed along the combined tables and de ositedon the truck table. The truck ta le is made large enough to hold severalconduit sections. In practice the inner one will be deposited on thetruck first and then the truck will be moved in on the platform 21 topresent an unfilled portion to receive a second piece of conduit. Thenumber deposited upon each truck is ofcourse not arbitrary: One, two, ormore pieces may be placed thereon, depending upon the size of the piecesand the dimensions of the truck. Supported by the standards 24 is aroller 38 which forms a support for the rack-bar 22.

A shield 39 of sheet metal is attached to the middle longitudinal frameof table 3 to protect the wheel 26 and rack-bar 22, from particles ofclay that work down through the tables.

The product coming from the mill will be an unbroken piece and will bedivided transversely by means of a wire cut-off. This wire 40 issupported by a frame 41 like an inverted U in shape. is clamped by aU-bolt 42 to a rock-bar 43. The latter is formed out of two angle barswhich are bolted at their ends to the opposite sides of plates 44. Thelates 44 have trunnions 45 by means of whic the rock-bar is pivotallymounted 011 the brackets 46. The space between the two angle irons formsOne stem of this frame a slot to receive the stems of the U-bolts forthe attachment of the frames 4] and because of the slot the bolts 42 canbe slid. in the slot to any desired position of the table so as to makethe cut-off at any desired place.

Fig. 7 shows the above construction clearly and also shows the means fortightening the cutting wire. This means consists of a lever 47 pivotednear its lower end at 43 to the frame 41, to the lower end of which anend of the cutting wire is made fast. The other end of the cutting wireis made fast to the opposite stem of the U-frame in the usual way. Theupper end of the lever 47 is hinged to a strap 49. The latter has aseries of perforations through which, when the wire is drawn taut, thepin 50 on the top of the frame will be passed to hold the adjustment.

51 is simply a handle for raising and lower ing the cut-off.

The table will be provided with a transverse groove for the cut-off wireto lay in be low the top face of the table when lowered, which enablesthe product to pass over it till .the length of a new section haspassed, when, by raising the cut-off the separation will be made. Itwill thus be seen that each vertical movement of the cut-off iseffective.

While the drawings show only a. single cutoff frame and wire attached tothe rockingbar, a plurality of such frames may be used, if desired.

The table 34 of the truck 33 is hinged by means of the hinges 53 to thecentrally pivoted platform or turntable 54, whereby the conduit sectionswhich are deposited primarily with their longitudinal dimensionstransverse to the truck may be turned to a position longitudinally ofthe truck, as illustrated in Figs. 8 to 11, inclusive. The turntablewill preferably have the ball bearings 55 or other bearings to reducethe friction.

A pallet 56 for the clay product to stand on when it is discharged fromthe truck, is placed in vertical position on its side edge on the trucktable and forms a stop for the clay conduit coming from the mill. Thepallet is retained in position by the removable standards 57. In somecases the pallet will be dispensed with, which makes it desirable todispense with the standards and for that reason the standards are maderemovable. This is secured by providing the standards with the rightangled base 58 which is inserted between the metal top of the table 34and the supporting portion below, in the slot 59 (see Fig. 14) and to)revent withdrawal longitudinally of the table 34, the base 59 isprovided with the right angle flange 60 to enter a corresponding grooveat the inner end of slot 59.

When the pallet is not used, the clay prod net is held from slipping offthe truck by frietion of a transverse board 62. The latter is hinged tothe U-shaped bar 63 to allow it to adjust itself so as to layflatagainst the clay article, and the arms of the bar 63' arepivoted at 64to the edges of the table 34 (see Fig. 13). One of the arms has theextension 65 by which the bar 63'is swung on its ivots in a manner tocause the board 62 to a vance or retreat from the clay product. A givenadjustment is held by springing the arm 65 under a pin 66. A series ofpins 66 provide for various adjustments of the arm. Direct and injuriouscontact of the board with the green clay product is revented by acovering 67 of soft materia such'as cloth.. Projections 68 from the endsof the board are provided to keep the board from turning over. When thefriction device above described, is not required, as when the pallet isused, the bar 63 is detached from its pivots and thereby removed. Theoperation of the truck will be fully understood from the drawin s.

A platform 70 may be used on one or both sides of my off-bearing device,depending on the surroundings. Ifthere is room enough on both sides, itwill be most convenient to wheel the empty truck from the near platformonto the movable platform, and then across upon a platform on the otherside, and thence to the dry house or kiln. But if there is room for aplatform on only one side of the machine, the loaded truck will have toback off to make room for an empty one.

The 0 eration ofmy invention is as follows: en a truck on the movableplatform is loaded, the movable platform is run out by turning the crankand the loaded truck is re laced by an empty one and the movable patform run back to the first osition. The mill, of course, has been ma'ng new material continuously and this is taken care of, first, by thetables 3 and 7 moving out from the mill until the table 7 is arrested bythe standards 18. Then the. table 3 begins to separate from the table 7,and by the time both tables have traveled their maximum distance, thetrucks have been exchanged and the movable platform is brought in by theuse of the crank and the twlo1 tables 3 and 7 are closed up against them1 While- I have described a machine for making conduit sections, it isapplicable for making other products out of clay, and I do not desire tolimit my invention to the manufacture of conduits.
